摘要

Optical rotator of beam paths includes optical element (1) on, or in rotation module, which contains impingement plane (2) and inclined exit plane (3). There is optical axis (5) along which extends impinging light beam through to exit plane.Orthogonally to optical axis optical element contains annular cross-section with at least one flat part bonded by secant. Typically, optical axis extends through centre point of annular cross-section. INDEPENDENT CLAIM is included for system of vibrometric measuring of turning object.
